I feel like I am going over and over this post, but I am having the same problem and I am not sure where to go next. Car overheated on the way back from Kansas City. I kept pulling over and letting it cool back off before going to the next exit and repeating it over and over again. During this I noticed that the coolant was not leaving the overflow bottle and going back into the engine. Finally on one of my last stops I splashed some water into the engine and I heard a pop and all the fluid from the overflow went into the radiator and the car instantly cooled off and I was able to make it back to the house.
I pulled the codes off my car and found that the fan clutch was under speed. Pulled the fan clutch and the wires were all burned out so while I was in there I replaced the fan clutch and the water pump. If you do one you should do them both, plus when I pulled it the water pump was warped. So drove it for a few days on short trips and when I went to pull my friends car on my trailer to the mechanic the car overheated on the way back. Pulled over waited for it to cool off and then was able to limp it home. Pulled the thermostat and it seems good but I replaced it anyways. Started it up and ran it to get it up to operating temperature and the temp started to rise again and the overflow is still not releasing into the engine.
I am thinking that it could be the radiator but figured I would search online and see any of y all have any ideas. Basically I replaced everything except the radiator itself. All the parts needed to be replaced, minus the thermostat. Anyone have an idea?
